In a few cases, such as in Cologne, the former ecclesiastical lord continued to claim the right to exercise some residual feudal privileges over the Free City, a claim that gave rise to constant litigation almost until the end of the Empire. Over time, the difference between Imperial Cities and Free Cities became increasingly blurred, so that they became collectively known as "Free Imperial Cities", or "Free and Imperial Cities", and by

The evolution of some German cities into self-ruling constitutional entities of the Empire was slower than that of the secular and ecclesiastical princes. In the course of the 13th and 14th centuries, some cities were promoted by the emperor to the status of Imperial Cities ( Reichsstädte ; Urbes imperiales ), essentially for fiscal reasons. Those cities, which had been founded by

The burgher status was usually an inherited privilege renewed pro-forma in each generation of the family concerned but it could also be purchased. At times, the sale of burgher status could be a significant item of town income as fiscal records show. The Bürgerrecht

It is rather a working-class sociolect with influences from the various dialects found in the area and changing even with the professions of the workers. A major common influence stems from the coal mining tradition of the area. For example, quite a few locals prefer to call the Ruhr either "Pott", which is a derivate of "Pütt" (pitmen's term for mine ; cp.

However, the occupation of the Ruhr caused several direct and indirect consequences to the German economy and government, including accelerating the growth of right wing parties due to the Weimar government's inability to successfully resolve the problem. On 7 March 1936, Adolf Hitler took a massive gamble by sending 30,000 troops into

Even after World War II, the term "Ruhr" may not have been in general use for the region: it was defined in Documents on American Foreign Relations (1948): "For the purposes of the present Agreement: (i) the expression 'Ruhr' means the areas, as presently constituted, in Land North Rhine–Westphalia, listed in the Annex to this Agreement." However, Lawrence K. Cecil and Philip Hauge Abelson still write in 1967: "In

After 1973, Germany was hard hit by a worldwide economic crisis, soaring oil prices, and increasing unemployment, which jumped from 300,000 in 1973 to 1.1 million in 1975. The Ruhr region was hardest hit, as the easy-to-reach coal mines became exhausted, and German coal was no longer competitive. Likewise

Instead in the Ruhr, the individual city boroughs and urban districts of the Ruhr grew in a rapid and parallel fashion independently of one another during the Industrial Revolution . The population density of

The welfare system provided a safety net for the large number of unemployed workers, and many factories reduced their labor force and began to concentrate on high-profit specialty items. As demand for coal decreased after 1958, the area went through phases of structural crisis (see steel crisis ) and industrial diversification, first developing traditional heavy industry, then moving into service industries and high technology.

In 1899 this led to a revolt in Herne of young Polish workers, who later established a Workers' Union. Skilled workers in the mines were often housed in "miners' colonies", built by the mining firms. By 1870, over 3 million people lived in the Ruhrgebiet and the new coal-mining district had become the largest industrial region of Europe. During World War I

By 1950, after the virtual completion of the by-then much watered-down "level of industry" plans, equipment had been removed from 706 manufacturing plants in the west, and steel production capacity had been reduced by 6.7 million tons. Dismantling finally ended in 1951. In all, less than 5% of the industrial base was dismantled. The Ruhr was at the centre of the German economic miracle Wirtschaftswunder of

Between the constituent urban areas are relatively open suburbs and even some open land with agricultural fields. In many places however, the borders between cities in the central Ruhr are unrecognizable, blending into one urban landscape due to continuous development across them. The replanting of brownfield land has created new parks and recreation areas in recent decades. The Emscher Landschaftspark (Emscher Landscape Park) lies along

The constitution of Free and Imperial Cities was republican in form, but in all but the smallest cities, the city government was oligarchic in nature with a governing town council composed of an elite, hereditary patrician class, the so-called town council families ( Ratsverwandte ). They were the most economically significant burgher families who had asserted themselves politically over time. Below them, with

6825-458: The region is defined by coal -bearing layers from the upper Carboniferous period. The coal seams reach the surface in a strip along the river Ruhr and dip downward from the river to the north. Beneath the Lippe, the coal seams lie at a depth of 600 to 800 metres (2,000 to 2,600 feet). The thickness of the coal layers ranges from one to three metres (three to ten feet). This geological feature played
6916-529: The river Emscher , formerly virtually an open sewer, parts of which have undergone natural restoration. This park connects strips of parkland running from north to south, which were developed through regional planning in the 1920s, to form a green belt between the Ruhr cities from east to west. During the Middle Ages, much of the region that was later called the Ruhrgebiet was situated in the County of Mark ,
7007-721: The southwest, than in the North and the East where the larger and more powerful territories, such as Brandenburg and Saxony, were located, which were more prone to absorb smaller, weaker states.

The Imperial military tax register ( Reichsmatrikel ) of 1521 listed eighty-five such cities, and this figure had fallen to 65 by the time of the Peace of Augsburg in 1555. From the Peace of Westphalia of 1648 to 1803, their number oscillated at around 50. Unlike the Free Imperial Cities, the second category of towns and cities, now called "territorial cities", were subject to an ecclesiastical or lay lord, and while many of them enjoyed self-government to varying degrees, this

The development of the region into an urbanized industrial area started in the late 18th century with the early industrialisation in the nearby Wupper Valley in the Bergisches Land . By around 1820, hundreds of water-powered mills were producing textiles, lumber, shingles and iron in automated processes here. In additional workshops in
7371-649: The void created by the extinction of dominant families, like the Swabian Hohenstaufen . Some voluntarily placed themselves under the protection of a territorial ruler and therefore lost their independence. A few, like Protestant Donauwörth , which in 1607 was annexed to the Catholic Duchy of Bavaria , were stripped by the Emperor of their status as a Free City – for genuine or trumped-up reasons. This rarely happened after

Historically, this loess belt has underlain some of Germany's richest agricultural regions. Geologically,
7644-451: Was a precarious privilege which might be curtailed or abolished according to the will of the lord. Reflecting the complex constitutional set-up of the Holy Roman Empire, a third category, composed of semi-autonomous cities that belonged to neither of those two types, is distinguished by some historians.

8099-540: Was now removed. France's eastern allies (the Soviet Union , Poland , Czechoslovakia , Romania and Yugoslavia ) concluded that since the French refused to defend their own border, they certainly would not stand up for their allies in the East. Hitler could now continue eroding the alliance system that France had built since 1919. On 16 October 1936, Belgium repudiated the 1921 alliance with France and declared its absolute neutrality. In October 1937, Belgium signed
